Were Those Strange Waves Rippling Across Earth Caused By Magma Shfits? (theguardian.com) 55
"Strange waves rippled across earth and only one person spotted them," reported Forbes, noting that the seismologist then "quickly put out an alert to see if other systems detected the same unusual wave."
"Seismographs picked up the waves as they traveled as far as New Zealand, Chile, Hawaii and Canada. In total, the waves were detected as far as 11,000 miles from their origin, ringing for 20 minutes or more minutes as they passed... As these waves rippled across the globe there were surprisingly no reports of anyone feeling the rumbling."
The Weather Channel now reports that "There was no earthquake large enough to have started these low-frequency signals. Scientists believed a magma shift caused the rumblings," citing a recent interview with Stephen Hicks, a seismologist at the University of Southampton. The Guardian reports: Hicks believes magma may suddenly have drained from a volcanic chamber about 10 miles under the seafloor near Mayotte, setting off the deep rumble that spread around the world. While strong enough to be picked up by sensitive seismometers, the vibrations would have been minuscule: far smaller than a millimetre. "It's something that you wouldn't perceive," he said. Pierre Briole, a geoscientist at Ecole Normale Superieure in Paris, has reached a similar conclusion. He believes that a third of a cubic mile of magma may have drained from a volcanic chamber under the seafloor, unleashing deep vibrations when its roof collapsed.
Much of the seismic sleuthing played out on social media with professional and amateur scientists working together. "Overall, [it has been] a fascinating demonstration of open science on Twitter and engagement between scientists and citizen seismologists," said Hicks.

Nope. Military Intelligence, which requested Trump to run for president, otherwise they were going to do a coup against the deep state. I'm completely serious, check https://qanon.pub/ [qanon.pub] for more details.
So they wanted more deep state?
How anyone can think that a billionaire, who has historically been so close to other politicians such as the Clintons, is not part of the deep state baffles me.

In this case simply rising sea levels mass adjustment. it will cause weird not very initially eventful outcomes, how ever it will inevitably create alterations in timing of seismic events, so earlier and more severe, some latter and less severe. All depends were the mass is going and where it is leaving. The end of the ice age would have created similar outcomes, that why legend has passed it down as a time of fire and ice, the same would have been true at the beginning of the event, shallower seas and pile

I made chili again. I had to do something with the leftover ground turkey. It was a big hit, but I fear magma shits may just be the start.

Drained? Drained into what? (Score:2)
This implies that there are large voids that the magma can drain into. The "10 miles" figure puts this shift beneath the earth's crust. If there are voids in the mantle, why aren't these shifts more frequent? How did the voids form? It would have made the article much more useful if this had been mentioned.
